Cargo aliases are a single command argv and cannot chain subcommands, so
`cargo verify = ["fmt --all -- --check", "check-all", "test-all"]` tried to
run a literal subcommand named "fmt --all -- --check" and always errored.
The pre-commit hook already runs the three checks as separate commands, so
it was unaffected. Drop the broken alias, drop the matching RustRover run
configuration, and reword every doc that told readers to run `cargo verify`
to instead run fmt/check-all/test-all as three commands.
